Title: Output circuit of photoelectric switch
Inventor: FUKUTAKE KATSUHIKO
IPC: H03K17/78
Filed: 1984-01-25
Abstract: PURPOSE:To obtain an output circuit of a photoelectric switch which can be used properly between the dark-on and light-on modes, by using a voltage inverting circuit which is set at a reverse level as separated by prescribed level of power supply voltage. CONSTITUTION:For a photoelectric detection inverting circuit B, the outputs A and A' are set a H and L respectively in a light input mode and vice versa in a light cut-off mode. While voltage inverting circuits C1 and C2 are set at H and L when the power supply has a level higher than 18V and vice versa with the power supply set lower than 18V respectively. Therefore the circuit C1 is set at H when 12V is applied to the power supply. Thus a trasistor TRQ3 is turned on and a TRQ4 is always kept off. Then an output TRQ2 is turned on and off according to the level of an output terminal A of the circuit B. The TRQ2 is turned on in a light input mode and produces a light-on output. On the contrary, the TRQ2 is always kept off when the power supply is set at 20V since the circuit C2 is set at H. Then the TRQ4 is turned on and off in response to the output A'.

Thus the storage device with high speed operation can be made.

Abstract: PURPOSE:To omit patterns and to form stable electrodes with good accuracy by specifying the size relation between images and electrode layers concerning the width of an electrifying blade and forming the electrodes on a blade substrate, then cutting the substrate to a prescribed size. CONSTITUTION:The rubber blade as the base body of the electrifying blade is formed by patterning and forming the rear electrode layers 3 of cruciform patterns symmetrically with an axial line as a boundary for the even number of sheets of a prescribed size by a printing treatment of a conductive coating compd. The images of a photosensitive drum 1, designated as J, are formed in the relation of J<width of the rear surface L<the width M of the electrifying blade. Non-electrode parts n, n' prevent charge leakage at the right and left end faces of the blade in the contact generator direction of the photosensitive drum. The substrate is then cut along the axial line to two sizes of the blades. After conductive rigid supporting members 4 are joined to both sides, the substrate is cut along the central axial line C-C. Two sheets each of the blades having the electrodes of the good accuracy are thus formed.

Filed: 1995-01-31
Abstract: PURPOSE: To set the accurate reset potential of a common connection terminal by connecting a reset means consisting of plural MOSFETs to the capacity terminal connected in common. CONSTITUTION: Two NMOS transistors TRs 400 are used as the means which resets a common connection terminal 200 by a power source 210, and a driving 'pulse ΦRES for reset is inputted to each gate. For example, when a control signal pulse is in the high level, the terminal 200 is reset by the power source 210, and thereafter, it is set to the low level to turn off the TR 400, and the terminal 200 is made floating. Meanwhile, a pulse the inverse of ΦRES having the phase opposite to that of the pulse ΦRES is inputted to the terminal 200 through a capacity 401.  Thus, the voltage change owing to the overlap capacity of the gate and the drain at the time of turning on/off the TR400 is cancelled by the voltage change owing to the capacity 401, and voltage changes at the terminal 200 are cancelled by each other, and the terminal 200 is accurately and quickly reset to the reset potential of the power source 210.
